SHUT ER-we RKER.

SPECIFICATION forming part of Letters Patent No. 393,401, dated November 27, 1888.

Application filed September 3, 1888. Serial No. 284,470.

To all whom it may concern.-

Be it known that I, JOHN F. SHATSIOK, a cltizen of the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improved Means of Opening and Closing Window-Shutter Blinds, of which the following is a full, clear, and exact description.

Myinvention relates to improvementsin that class of outside window-shutter blinds which are opened and closed by bevel-gearing and spindle from the inside of the window, and has for its object to automatically lock or hold the shutter-blind when in the open, closed, or intermediate position, to maintain the bevelwheels in full gear, and to protect the same from ice and snow.

My invention consists in a bevel wheel or segment carried by the shutter-blind and engaged by a bevel-wheel fixed on a hollow spindle extending horizontallyinto the side of the window-frame, a square (or other suitably shaped) spindle inserted within the hollow spindle and having preferably a circular end portion projecting through a toothed plate, which is fixed to the jamb of the window-frame on the inside of the building, a sleeve or bush having keyways adapted to slide over keys or feathers on the circular portion of the square spindle and formed at opposite parts of its circumference with projections having teeth for gearing into those of the toothed platc,a spiral spring surrounding the circular portion of the square spindle between its outer head and the sleeve or bush, a fork or yoke pivoted horizontally by its shank in the outer end of a cap or casing inclosing the above parts, the ends of the fork having inwardly-projecting studs or pins bearing upon the inclined or camshaped edges of circular-shaped webs connecting the extended projections of the sleeve or bush, and a knob or handle secured to the shank of the fork or yoke on the inside of the window, the whole operating so that by a partial rotation of the knob or handle in either direction the studs or pins of the fork riding over the inclined edgesofthesleeve or bush constrain the latter endwise along the circular portion of the square spindle until the teeth of the sleeve are out of gear with the toothed plate,when by turning the handles to a further (No model.)

extent the spindles are rotated, and by the action of the bevel gear the shutterblind opened or closed radially on its hinges. On releasing the handle the spiral spring throws the toothed sleeve into gear again with the toothed plate, so as to prevent the rotation of the spindles, and thereby lock the shutterblind in any desired position.

My invention also comprises a cap or covering for the bevel-wheels and a device for preventing any vertical play of the shutterblind on its hinges under the action of the full gear at all times.

On the accompanying drawings, Figure 1 represents a side sectional elevation of my invention applied to an outside shutter-blind seen in end elevation, broken away; Fig. 2, a sectional plan thereof; Fig. 3, adetachedview of the parts seen to the left of Fig. 1 in altered positions; Fig. 4, a transverse section on line 1 1 in Fig. 3 looking to the right hand, and Fig. 5 a similar view looking to the left hand; Fig. 6, a transverse section on line 2 2 in Fig. 2, broken away; Fig. 7, a detached sectional view of the square spindle and sleeve forming parts of my invention, as seen to the left of Fig. 1; Fig. 8, a transverse section on line 3 3 in Fig. 2, broken away; and Fig. 9 a section on line 4 4 in Fig. 8, like letters of reference denoting like parts in all the figures.

a represents a window-shutter blind'(broken away) provided with the ordinary upperhinges (not shown) and with a lower hinge-bracket, b, from which projects an upper arm, 1), carrying in a plane at right angles to the blind a a bevel-toothed wheel-segment, 0, which is mounted axially over the upper end portion of the upright hinge d, projecting from the op posite hinge-bracket, e, the latter being secured to the window-framef in theusual manner.

Projecting from the screw plate of the hinge-bracket e, at right angles thereto in the direction of the adjacent portion of the window-frame f, is a bracket, 5 formed with a slotted bearing, 9, in which is mounted the outer end portion of a circular spindle, h, having a collar, h, bearing against the outer face of the bracket 9, and an outer, preferably square, end, h for receiving a vertically arbevel-wheels, and so maintaining the latter in ranged bevel wheel, a, which gears into the upper bevel-segment, c. The spindle h is in sertcd for a suitable distance within a corresponding hole cut horizontally through the upright of the winilowframef from the out side of the latter to the interior of the building, the said spindle h being formed with a central square (or other suitablyshaped) longit ndinal recess, It, into which isinserted from the inside of the window-framef acorrespondinglyshaped spi udlc,j, having an end portion, j, (prcl'ci ably ci rcnlar.)which projects th rough a l'ace plate, k, fixed against the insidejamb of the windowframe f, the said plate 75 having teeth l projecting at right angles therefrom and arranged radially to and atasuitable distance from the circular portion j of the spindlcj. At opposite parts of the circular portionjof the spindlej are longitudinal keys or feathers m, Figs. 5 and 7, which engage in corresponding slots or keyways, a, formed in a sleeve or bush, 0, placed around the spindle j, and having at opposite parts of its circumference radial projections 11, at one end of which are teeth q, corresponding with the teeth I of the plate In, and at their other end extended portions p, which are united radially to the circular portion j of the spindlej by webs r, the edges of which facing the teeth I and q are inclined, respectively, from their junctions with the extended projections p to the circumferential center of the webs 1' toward the outer end or head, 5', of the spindle j j, between which head s and the sleeve or bush 0 is placed, around the circular portion j of the spindle a spiral spring, 1', which normally maintains the sleeve or bush 0 with its teeth (1 in gear with the teeth l of the plate k.

Inclosing the circular party" of the spindle j and sleeve or bush 0 with their appendages is a cap or casing, 11, in the outer end of which is pivoted, centrally with the spindle j j, the shank not" a fork or yokew, the arms of which extend within the casing it along the outside of the sleeve or bush 0 and terminate in inwardlyprojecting studs or pins 10, which overhang and bear respectively upon opposite parts of the inclined edges of the webs r, (seen more particularly in Figs. 2, 3, and 5,) the spindle j j being centered and held endwise within the circular spindle It by a stud or projection, :v, on the shank i between the arms of the fork to. The outer end of the shank '22 passes through the bottom of a cup, 9 and is formed thereat with a cranked arm, .3, by which the shank o and cup 9 are secured together, and to the knob or handle a (partially embedded in the cup y) by a screw, 0, which passes through a slot, d, in the side of the cup 3 and through a corresponding slot, 0, in the cranked arm a, into the knob or handle a, so that the latter cannot possibly be rotated without the yoke 10.

In operation, by partially rotating the knob or handle a in either direction from the inside of the building the studs or pins to of the fork to ride over the inclined edges of the sleeve or bush 0, and thereby constrain the latter endwise along the circular portion j of the spindle j until the teeth of the sleeve 0 are out of gear with the teeth 1 of the fixed plate 7., when by a further rotation of the handle a the sleeve 0, acting on the keys or feathers 121., rorotates the square spindle j, which, carrying with it the circular spindle h and bevel-wheel i, rotates the segment 0, and so opens or closes the shnttenbliud a radially on its hinges at will. By releasing the handle a the spring 15 (previously compressed) returns the fork w and sleeve or bush 0 to their normal position, as seen in Figs. 1 and 2, whereby the teeth q of the sleeve 0 are again thrown into gear with the teeth Z of the fixed plate is, which prevents the rotation of the spindles j h, and thereby locks the shntterblind e in any desired position from closed to fully open. For opening the shutter-blind a into the position seen in Figs. 1 and 2, the handle a and fork to are turned to the right hand, as seen in Figs. 3 and 5, and to the left hand for closing the shutter-blind a.

To protect the bevel-toothcd segment a and wheel i from the weather the upper surface or back of the segment 0 is surmounted by a hood. or cover,f, which overhangs the gearing c i, and prevents the access of ice and snow thereto.

Around the hinge-pin (I, immediately below the bevel-toothed segment 0, is a projecting ring or beading, i, (see Figs. 1, S and 9,) which is cut away at a part of its circumference for allowing passage to a hook, in, which depends from the lower side of the bevclsegment 0 so that when the latter is passed onto the hinge-pin (Z the hook catches under the heading 2" and prevents the rising of theshuttier-blind u, from the action of the bevel-wheel t, which is thereby maintained in full gear with the segment 0 at all times.

By the use of the slotted bearing y in the bracket 7 the bevel-wheel i is always held in true gear with the segment 0 of the shutterblind a.

The great advantage of my invention is that the shutter blind a may be automatically locked from the inside of the window in the closed or open or any intermediate position, so that it cannot be moved from the outside.

I claim as my invention- 1.. The combination of a bevel wheel or segment 0, carried by hinged shutter-blind a and engaged by bevel-wheel i on spindle h, spindle j.inserted within spindle h and having portion. j projecting through face-plate k,formed with teeth t and fixed to inside of window-frame f, sleeve or bush 0, adapted to slide longitudinally on and rotate with spindle jj, andhaving projections p1) and teeth q, webs r, connecting said projections 1), spring 15, fork or yoke 10, pivoted by shank o in casing to, and having pins 10 and projection 00, and cranked arm .0, having slot 0 and located in cup y, having slot d, and screw 0, with knob or handle a, substantially as showmand for the purpose described.
